Intelligent acoustic monitoring platforms and sensor networks for use in industrial applications
The ZIM project IMPASA
In Production 4.0, sensors provide valuable information for monitoring the condition of plants and processes, for quality inspection, and for predictive maintenance. The ZIM project IMPASA aims to further develop an open, intelligent sensor platform for use in industry that relies on acoustic event detection.
The acronym IMPASA stands for »Intelligent acoustic monitoring platforms and sensor networks for use in industrial applications«. IMPASA is funded by the Federal Ministry for Economic Affairs and Energy (BMWi) and the Central Innovation Programme for small and medium-sized enterprises (ZIM). »Ears for the machine hall« are being developed in the project. These are intelligent acoustic sensor systems for industrial applications. The sensors are used for machine, plant and process monitoring and are able to indicate acute machine faults, wear or quality defects by analyzing the recorded airborne and structure-borne sound.
The project focuses on the use of distributed sensor technology and its combination to generate additional spatial information. Starting from the sensor system of point omega AG, essential adaptations in software and hardware are to be carried out. These include
- the improvement of multi-channel microphoning including audio pre-processing,
- miniaturization and mobile availability of the system
- as well as the improvement of distributed AI.
Wireless communication channels simplify the scalability of the system and thus address complete technical infrastructures. In a next step, the distributed sensor nodes will be combined into application-dependent sensor networks in a freely configurable graphical user interface to be developed.
Intuitive options for commissioning, operation and maintenance are to be tested. Data-driven business models »as a service« form the industry-open business focus of the project. Data security is ensured by 100% data processing on the sensor unit.
In order to align the developments in the project closely to market needs, selected end users will be integrated into the project at an early stage via pilot applications. This is to ensure that IMPASA produces solutions of high relevance to real challenges.
